Title: Improved means for controlling the pressure in fluid-pressure systems
IPC: F22D5/14
Filed: 1920-07-26
Abstract: 172,355. Marks, E. C. R., (Veenschoten, V. V.). July 26, 1920. Stop-gear. - In apparatus controlled by variations in the pressure of a fluid, a valve is arranged to admit a second fluid when the pressure of the controlling-fluid falls by a predetermined amount. Fig. 1 shows the application to a boiler feed-pump, having a valve in the feed-pipe controlled by the level of the water in the boiler. The stop-valve 12 in the steam-pipe 11 is controlled by a cylinder 13, the upper end of which is connected by pipes 25, 19 to the boiler feed-pipe, while the lower end is connected by a pipe 21 with the steam-pipe. The pipes 25, 19 communicate by means of a casing 14, Fig. 2. A valve 22 in the casing is acted on on its upper surface by the pressure in the feed-pipe and by a spring 35 regulated by a screw sleeve 39. The lower surface of the valve is acted on by steam and a head of condensation water in a pipe 20 communicating with the boiler. In the event of a great fall in the pressure in the feed-pipe, the water and steam in the pipe 20 lift the valve 22 and pass by the pipe 25 to the cylinder 13, thus closing the stop valve 12. In order to re-start the pump, a stop valve 51 in the pipe 20 is closed. The pressure of the spring 35 may be so regulated that slight fall in the feedwater pressure is sufficient to open the valve 22.

Title: Method and apparatus for the attainment of regular burning of liquid fuel
IPC: F23D5/00
Filed: 1925-09-08
Abstract: 249,017. Erichsen, V. H., and Falkentorp, G. E. Sept. 8, 1925. Open tray burners; vaporizing apparatus; oil supply; burners, materials for. - Stoves, kitchen ranges, furnaces, &c. are heated by one or more combustion units each comprising a trough 3 to which oil is supplied from a reservoir 1 and a refractory block 6 suspended or supported between walls 12 above the level 31 of the fuel in the trough 3. The heat radiated by the block causes vaporization of the fuel in the trough 3 and the vapours burn at the surface of the block with air admitted through a regulable passage 10 and passing to the block through recticulated, perforated or porous plates 8. The plates 8 and walls 12 may be seated and packed in sand 15, 16 in a bottom container 4. The fuel supply from the reservoir 1 is controlled by a cock having a plug 17 formed with an angled hole 19 which in the normal working position communicates with a cavity 24 in the cock body 18 to which the oil flows by gravity from the reservoir through a small passage in a screwed plug 25. The rate of supply to the trough 3 is regulated by adjustment of the plug 25 or of the coil level in the reservoir 1. The oil may be supplied to the reservoir 1 by means of an inverted bell, closed chamber, or barometrical pipe 30, the outlet of which is adjustable in height. A spring- pressed needle 27 having a grooved guide block 32 is provided in the cavity 24 for clearing the passage 20. At starting the plug 17 is turned to bring the hole 19 into communication with an aperture 23 in the body 18 thereby allowing the oil fuel to pass freely to the trough up to the level of the bottom of the block 6. The cock is then turned so that the hole 19 communicates with the passage 22 and the oil is ignited through an aperture 14 in the burner wall normally closed by a door 13. The block 6 may be of Kieselguhr such as that found in Denmark and known locally as " moler." When several units are used each may have a separate fuel supply so that a step-by-step control of the, heating effect may be obtained.

Title: Electronic Control System
IPC: H02P7/292
Filed: 1966-05-20
Abstract: 1,150,903. Control of D.C. motors; rectifying. WARNER & SWASEY CO. 20 May, 1966 [24 May, 1965], No. 22483/66. Headings H2F and H2J. [Also in Divisions G3 and H3] In a system wherein the mean current supplied from an A.C. source to a D.C. motor is varied by varying the firing angle of a thyratron or thyristor in the supply circuit, triggering is effected by a plurality of pulses when the magnitude of a cyclically varying control signal reaches a predetermined threshold level. The output 26a of a tachogenerator which may be A.C. or D.C., is amplified by transistors 90 ... 92 and mixed with a bias signal 30 which is A.C. at mains frequency. The result varies the conduction of a transistor 64 and hence the current through a tunnel diode 70; at a particular level this switches to its non-linear condition and causes conduction of a further transistor 66, the resulting output pulse being differentiated and converted to a pulse of constant length at 75, which is applied as one input to a gate circuit 34. A second input is from a continuously running transistor oscillator 36, whose pulses are thus passed to an amplifying and pulse shaping stage 38 to trigger the thyratron 50 or thyristor (111, Fig. 3, not shown). The pulses are of relatively high frequency so that if the first fails to trigger another rapidly follows. For reverse rotation an oppositely poled thyratron 51 or thyristor is triggered by a separate circuit; the bias signal is applied to both circuits with 180 degrees phase difference so that the error signal effectively phase advances the bias to the circuit for appropriate direction of rotation.

Abstract: 1,154,361. Card readers. INTERNATIONAL COMPUTERS Ltd. 1 Sept., 1966 [1 June, 1965], No. 23400/65. Heading G4M. [Also in Division H4] A punched card reader which forms part of a telephone subset or which may be connected to the telephone line at the subset successively scans possible hole positions in a column as the card moves past column by column, a set of hole sensors being arranged in a line skew to the columns, and transmits a signal to line each time a hole is sensed. In a mechanical sensing arrangement shown in Fig. 1 a card carrier 10 which supports the card 13 is moved to an operating position to wind the spring 17 which then drives the carrier back at a substantially constant speed, determined by governor 18, to permit successive sensing of the columns of holes, by contact pairs formed by the blade contacts 24 and roller contacts 15. The shaft 14 and contact pairs are skewed with respect to the card so that only a small number of possible hole portions are covered by contacts at any one time, this arrangement coupled with a distributer which successively connects the contact pairs to an outside circuit ensures the successive sensing of the possible hole positions in a column. If the holes are small compared with the column spacing only one hole is sensed at any one time and the distributer may be dispensed with. A clock pulse may be generated for each possible hole position sensed and their correlation with the hole signals determines the encoded information. The card may be sensed photo-electrically.
